RE: Which Climbing Stand??
I can't comment on the Lone Wolf or Ameristep, but I have a Summit Viper and like it a lot.
It goes on the tree easy with its cable system, it's sturdy and comfortable, and not that heavy to hike in with.
I like the stirrups and bungee on the bottom piece much better than boot straps.
I've been real happy with it. I have 4 climbers, but I'm usually reaching for my Viper when I head to the woods.
